How can I get values from Data Source in Script Assertion?

Thank you for your answer.

I want to use property in Scipt Assertion.
First time I would use Xpath assertion. But I couldn't use it.
Because I compare response code with property...


I want to use this way..
example in Script Assertion>

if (messageExchange.responseStatusCode = [from DataSource property])
....




Is it possible

the hierarchy of my projecttestsuite :test step1 script assertion
- testcase
- - data source
- - test step 1
- - data source loop

thanks for your time
